At Crafty Software, I architect and build low-latency backend services and blockchain infrastructure in Go for EVM, Cosmos SDK, and Solana networks. I optimize distributed systems for high-throughput transaction processing.
Previously, I led payment-platform rewrites at VR_BANK, AcquiroPay, and A2A, building PCI DSS-compliant systems processing up to 1,000 TPS and growing a team from one to four engineers. Across fintech, digital banking, microloans, and e-commerce, I've delivered microservices, cloud-native platforms, CI/CD pipelines, and production-grade backend architecture.
